IELTS means of proof

[Leaver]

Does anyone know what tyep of proof is required to prove english language knowlege via IELTS?

The guidance on the tests says "For tests taken before 6 April 2013: Test report form
For tests taken on or after 6 April 2013: no documents required (Scores must be verified using the Cambridge English online system using name, date of birth and passport number)"

Says no documents required, how will they know?

I have passed but still waiting for my certificate by mail. I log in but there is no option to print the score , just a very minimal pages, not even mentioning my name (passport number and DOB).

Not sure if i should wait for the original?

cheers
